RECORDING DEVICE FOR LIQUID PUMPS.

Apulication filed October 20, 1921. Serial No. 508,952.

T u ail whom it may concern.'

Be it known that I, ATHERTON B. SNYDER, a citizen ofthe United Sta-tes, and kresident of Grass Valley, county-of Nevada, and State of California, have invented a new and useful Recording Device for Liquid Pumps, l'

of which the followingisfa'specification.

The present invention relates to'improvements in recording devicesfor liquid pumps and is desi ed with particular referenceto oil dispensing pumps such as are commonly used in garages and automobile supply stations. Particular attention is called in this connection to my (3o-pending. application Serial No. 508,951 whichdescribes-a similar recording device vfor gasoline vdispensing pumps, the principal diierence between the two ldevices being that in gasoline 'dispens-v ing pumps a h ose is vcommonly used'as a dispensing means while inoilv dispensing pumps it. is common to use a faucet for the same purpose. Since my device in both cases is closely associated with theparticulardispensing means and is so constructed that the atter cannot be properly used without causing a record to be made of the quantity with'-l drawn, it became necessary-'to provide two different recording devices, one being adapt ed toco-operate with the hose used as dis,- pensing -means while the other described in the present application is adapted to be used in co-operation with the, faucet.

As stated in my co-pending application the particular object of my invention is to provide ,a recording device thatwill eliminate any of theA mistakes or errors commonly made by the operator which consist principally in the failureto properly record all the scales made. i f

.With these objects in view I have illustrated the preferred form of my invention in the. accompanying drawing, in which Fig-l ure 1 represents a side view of my recording device, thecover being removed so as to disclose the interior; .Figure 21a vertical cross section through the device along line 2--2 of Figure 1, and Figure 3 an assembly side elevation of the oil pump as commonly used It will be understood that I do not'wish to confine my device to oil pumps as such. but wish to be protected on the same in connection with any liquid dispensingl pump adapted to be used in connectionwith the same.

Figure 3 shows the oil dispensing pump (1) as commonly used in oil dispensing stations. .The same is actuated in a well known e manner not shown in the drawing by means offthe handle (2). My recording device (3) included in the box4 (4) isattached to thc slde of the pump as shown in Figure 3. The

discharge pipe (6) of thepump is controlled by the valve (7) normally forced against the valve seat (8') by the sprin rounding the valve rod (10). 1 e valve is n `actuated by a bell crank lever (5) pivotally supported on the pump as shown at (15) and having a forked end (20) engaging the end of the valve lrod between two collars (25). The other arm of the lever (5) extends tc within close proximity with the outlet of tbc faucet and supports in a central portion the bar (41) which co-operates withthe pump-v ing mechanism in actuating my recording device and which will be referred` to more particularly hereafter. Suilice it vto say at the present time that the raising of the free end of the lever (5) opens the valve (7) and simultaneously causes the bar` (41) to move upwardly lagainst the resistance of the spring (76) secured between the bar (41) and the side (77) of the box (4), while the release of the free end of the lever (15) closes the valve and causes the bar (41) to move Y downwardly undery the inlluence of the spring (7 6). The free end of the lever (5) is raised by the operator when he wishes to withdraw oil, by striking the same from below with the oil receiving receptacle.

The detail construction of the recording mechanism is shown in Figures 1 and 2 from which it will be seen that the principal actuating means :for the recording device is the shaft (11) which is connected either directly or through a train/of gears, not shown in the drawing, to the handle (2) so that whenever the handle (2) is operated the shaft (11) `will rotate in a predetermined manner.

-The 'shaft (11) has keyed thereto a pinion (12) which engages a gear wheel (14) loosely mounted on the shaft (16) extending parallel to the shaft (11) and supported 1n the walls of the box (4). The shaft (16) has also loosely mounted thereon the recording wheel (17), the rim of which is graduated, as shown in Figure 2, andy which forms an integral part of the sleeve (18) carrying the bevel gear (19) bearing against the collar (20) rigidly secured to the shaft (16). A spring 21) wound on the shaft 16) and extending between the wall (22) of the box (4) `and the gear wheel (14) presses the lat (9') sur-k Yter gear wheel into operative contact with the recording wheel (17 This contact is `sufficiently intense to transmit rotary motion from the gear wheel (14) totherecording wheel (17 and the b evel gear (19), but is not suicient to transmit motion the opposite Way so that the gear wheel (14) will turn the recording wheel (17) but the ,latter will not turn the former on account of its heavier load. The particular object kof this arrangement will appear as the description proceeds. The bevel gear (19) engages a second bevel gear (24) at the lower endof the vertical shaft (26) extending through the top of the box and ending into a worm (27) engaging the worm gear (28) mounted on the transverse shaft (29) whichv latter shaft carries the hands (9) of the diall (8).-

It will be seen that in the device thus far described a turning of the handle (2) will cause the recording wheel (17) to rotate so dicate the total oil withdrawn and is constructed along well known lines, and therefore not described in detail, it being ficient to state that the recording device (38) brings a figure corresponding to the total oil withdrawn in operative proximity with the printing device (31) at the same time that the recording wheel (17 brings the fig-v ure indicating the quantity of oil withdrawn during the last operation into the same relation with the printing device; vThus after a quantity of oil has been withdrawn we find the hand on the dial indicating the oil withdrawn during the last. operation, the wheel (17) bringing the same figure and the re-l cording machine (38) the total figure op posite the printing device.

sired amount of oil he releases the lever '(5), which is shown as pivotally supporting the vertical bar (41) extending through the box and provided with teeth (42) and (43) at two opposing'sides. The teeth (43) engage a cog wheel (44) loosely mounted on the' shaft (46) and provided with a pawl (47) adapted to engage a cam (48) rigidly A when the drums rotate.

vthecog whee .fthe lever (5) is raised gagement with the cam (48). and .'that the cog wheel (44) has to rotate through about one-fourth of a turn beforey the p awl engages'the cam.y The shaft. (46) carries thc drum (51) with which is operatively associated asecond drum (52).y idling on the shaft (53) so that the strip of paper (54) emanatingfrom the roll (56) may be received between the two drums and advance also provided with a dog (57) lpivotingon the pin (58), the position of the dog being defined by the stop (59) and the spring '(61) forcing the extreme end of the dog against the stop. On the downward travel vofthe bar (41) lthe which comprises a lever (64) pivoting on the shaft (66) and carrying a'tfr'a'nsverse printing Vhammer (67) disposed in operative relation to the single recording wheel (17) as well as the totalrecordin machine (38). The other arm ('68) of the ever (64)4 point (62) of the dog' (57)* engages the point (63) of the printer (31) is connected by the spring (69) to a suitable stationary support. When the lever (5) is released it forces the bar (41) downwardly,

the teeth (43) engaging and rotating .thev cog wheel (44)*while the dog (57) engages the printing lever (64). It willbe remembered lthat the cog wheel (44) is inoperative during the first quarter of its turn sov that the dog (57) can force the printing lever (64) downward against the resistance of the spring (69) until through the changed position of the lever (64) the dog losesits hold on the lever and the latter is violently' thrownV against the two .recording wheels (17) fand (38) and the strip of paper ,(54)

interposed betweenthe recording wheels and the printing lever so that 'the figures on the wheels indicating the record to be made 'are printed on the-paper. When this vis donel the pawl (47? engagesthe cam (48)-so that (46) and with it the drum (51), which (44) begins to rotate the shaft v.

through its .cooperation with the drum (52)* pulls the paper forward and pushes the record previously made through the slot (72) in the side of the box where the same may be manually separated from the ystrip (54). After the operator has withdrawn the de- It will be seen that-this last operation has `not changed'the position of the'recording It will be rememberedV that the re'- cording wheel (17) is mounted loosely on the shaft (16)1so that normally the rotation of the shaft (16) does not affect thef-record-- ing wheel (17 0n the downward motion forcing the pawl into engagement with the recess. 'In this manner thevrecording wheel (17) which was advanced from zero to av figure corresponding to the quantity of oil withdrawn during the last operation is now further advanced so as to go back to zero. As has been 4previously remarked, the recording wheel (17) is connected' with the gear Wheel (14) in such a manner as to allow of rotary motion of the recording wheel independently of the gear wheel (14). The

advance of the recording wheel (17 to zero is transmitted to the hand on the dial by "xmeans of the bevel gears (19) and (24),

the shaft (26), the worm (27) and the gear (28) so that when the lever (5) is raised the recording wheel (17) as well as the hand (9) on the dial are advanced' to zero, while the total recording machine (88) remains unaffected.

Briefly stated, the apparatus works as follows: Upon turning the handle (2) which actuates the pumping mechanism the shaft ('11) is actuated to rotate and to turn the gear wheel (14) and through it the record- 1ng wheel (17 Assuming that the shaft (11) is turned counter-clockwise looking at it from the right side in Figure 2, the recording wheel (17) is turned clockwise and a certa1n (figure, say 5, is brought op-posite the printing device. Simultaneously the hand on the dial hasbeen moved to indicate the ligure 5 on the latter through the gear train described hereinabove, while simultaneously the figure 5 has been added to the total figure indicated on the total recording device (38). Releasing the lever (5) which is pressed upward by the operator during the dispensing operation; causes the bar (41) to slide down- Wardly to actuate the printing lever (31) by means of the dog (57) and to pull the strip of paper (54) forward so as to expose the printed record outside of the box for manual removal. During this operation the shaft (16) has been rotated in counter-clockwise direction without affecting the recording wheel (17) since the recess (81) in the shaft (16) does not engage the pawl (79) on a counter-clockwise rotation. The next step is the raising of the lever (5) for the withdrawal of a new quantity of oil which 'causes the bar (41 to slide upwardly thereby rotating the s aft (16) in a clockwise direction. On this motion the'shaft engages the pawl (7 9) as soon as the recess (81) reaches the point of the pawl and then turns the recording Wheel (17) into its original posiv tion by advancing the same in the same di'- rection in which it was originally rotated;

that is, if the recording wheel is graduated the raising of the lever (5) at the time of. the next withdrawal from 5 through the remaining liguresto 25 or its point of commencement. lThe hand on the dial moves in .exactly the same mannervas the recording wheel. It will be noted that due to the construction of the dial the hand cannot be turned in either direction manually since the Worm gear is employed for its operation. Thusv whenever the hand on the dial indicates any other figure than zero there is only one way of returninor it to zero and that is by releasing the lever l(5) and raising it a ain. As we have seen, the releasing of the ever causes the record to be printed on the strip of paper so that when the hand on the dial indicates any figure except zero it cannot be returned to zero except after the record has been properly printed on the strip of paper. It will be readily understood that instead of one strip of paper two strips may be intro duced so as to provide an eXtra copy for the customer.
